From the post

Opus 5.5’s performance on this Three.js game build is nuts. I gave it a heavy game-building task and the result is way beyond what I expected: • Full playable kart racer • Multiple race modes • Proper menus/UI • Track environments • Multiple racers • Lighting, effects, scenery • Actually feels like a game instead of a tech demo Playable build : https://t.co/RHdwH3LgQl This is one of the strongest game outputs I’ve seen from a model. Opus 5.5 is a serious model.
